The GT's did run well at Laguna Seca, but if you watched the C7.R's and 911's were busy playing bumper cars all race. The results below speak for themselves.

1st Race (Daytona)
C7.R = 1st & 2nd
GT = 7th & 9th



2nd Race (Sebring)
C7.R = 1st & 9th (9th place finisher, wrecked by Porsche while leading)
GT = 5th & 8th



3rd Race (Long Beach)
C7.R = 2nd & 9th (2nd place finisher, wrecked by Porsche while leading)
GT = 4th & 8th



4th Race (Laguna Seca)
C7.R = 4th & 7th (wrecked by Porsche while leading)
GT = 1st & 6th

Also..the class the FGT is running in (LMGTE-Pro, or Le Mans Grand Touring Endurance Professional) for the 2016 24 hours of LeMans includes the C7.R, the Ferrari 488, the Porsche 911 and the Aston Martin Vantange.

Hope this helps clarify the exact nature of the FGT at LeMans.

Well the guy was claiming that Ford chose to run the Ecoboost instead of the Voodoo, because of engine size cap. Which is in fact BS!

Why they chose to run the already developed Ecoboost engine has no bearing on the fact that they could have developed a N/A V8 with larger displacement.

Because the cost involved in creating an entirely new block and engine tooling line to accommodate more than 5.2L would have been too high. Due to the modular engine assembly line, all current V8's have to hold to the current (I think) 100mm bore centers, which limits how large of a bore and bore spacing you can run.

There is a *displacement* cap for what they wanted to run and promote, which is the EcoBoost system. They had a specific power output they wanted and a specific performance metric to meet, they felt they couldn't do that with a N/A V8, obviously, so they went with the EB for that reason and the above reasons. This is no different from Team Corvette going FI for the Z06.

FIA WEC finishes as follows...

Keep in mind the C7.R is not a factory team Chevy. It's a private team.



Race 1 (Silverstone)
(LMGTE-PRO) Ford GT = 4th & 5th (7 total in class)
(LMGTE-AM) Chevy C7.R = 3rd (6 total in class

Race 2 (Spa)
(LMGTE-PRO) Ford GT = 2nd & 6th (7 total in class)
(LMGTE-AM) Chevy C7.R = 3rd (6 total in class)

The voodoo engine could race in the GTLM class and The FIA class that's why I said BS.

1. That's fine that they feel they couldn't do it. Chevy doesn't seem to have any issues pulling it off though. You can drop the price argument. Do you think either Ford or Chevy is pinching penny's with these race cars? I'm sure it wasn't cheap for Chevy to develop the LT5.5 either, but they did it.
   
2. Yes it is different. VERY DIFFERENT. You are talking about a street car that must meet emissions regs and a race car engine that only has to meet class restrictions.

Yeah that was a bunch of crap with the 911 spinning out the Corvettte so the second car could get the win. Mad as hell to see that and team Porsche get the win. But that's the way things worked out.

well I was half right lol. as Speedislife pointed out the displacement cap is 4.0 for forced induction cars, that is the route they chose to go. It is what is.

You do realize that Chevy had multiple more options in terms of engine production lines to base the 5.5L motor off of, right? Ford has 2..a truck line and the current Mod Motor line. It would be entirely stupid and financially irresponsible to create an entire new engine tooling line, foundry, etc..just to build race motors for one vehicle when they have a race proven motor system already developed and available.
Cost IS a factor with these race programs, and no company has bottomless budgets for these events. Ford has to answer to their shareholders ultimately for their expenses, you'd have to be daft to not realize they are beholden ultimately, in terms of cost, to what the shareholders are happy with.

And no, it's not any different, just different justifications for the same decision. You don't know it was ONLY emissions that scuttled the N/A motor for the Z06..unless Team Corvette has very clearly said it was ONLY emissions that kept the n/a motor on the shelf. It could have been emissions and durability, or emissions and warranty concerns, or etc etc...see what I mean?

Wait until the race is done before anyone calls "BS" on Ford and the FGT..if they win, then they win. If they beat the C7.R's, then they do. If they lose, they lose. If they're beaten by the Corvettes at LeMans, then they'll have to try harder next year. Even the legendary GT40's had trouble their first one or two seasons, then came back and swept the race 3 times.

True but the Voodoo engine is N/A so a racing engine derived from it would fit in the N/A under 5.5l category. So you were 100% correct in your statement.

I'm not even sure I know what points your trying to make anymore.

The "BS" statement was in regards to the statement that the Voodoo engine wouldn't meet class restrictions. Plain and simple that statement is false. It would fall in the same 5.5l or under N/A engine rule.

As far as the race cars go I am clearly a Corvette Racing fan, but I'm excited to see the GT's race again at LeMans. Based on the results in both racing series this year (which I already posted in this thread) I don't see the GT's being a top contender for a win this year. That being said no one here called any BS on the GT race cars. That was a whole other topic being discussed about the voodoo engine.

Not sure what your point about the production of the engines are. I'm almost certain that none of these racing engines are built on a production line. They may be limited to using a block configuration similar to that of the production car, but that doesn't mean they mass produce the racing engines.

Per the link below the new performance center for GM where all the racing engines will be assembled only contains 10 engine assembly bays. Not just for the LT5.5 but also the other engines listed below.
